Question

Which rule describes the transform that is a reflection across the y-axis?

Answer 1

Answer: The reflection rule.

Step-by-step explanation:

the y-axis is the point (-x,y). Reflect over the y = x: When you reflect a point across the line y = x, the x-coordinate and y-coordinate change places.
